This reverts commit 9f0359d78f9facc38418e32b0e8c1bf6f99f0d26 in an attempt to
make the tests pass again. The CI failure from that merge should be unrelated
to this commit.
This reverts commit b822e841cda0adabe3fec260ff51c18508f7ee32, reversing
changes made to 0c99ba1eab63865592bb084feb271cd4e4b0357e.
This caused a CI failure when it landed in master branch.
This makes all union test cases succeed.
`rem` was also implemented as all we had to do is enable the instruction.
Loading and storing values based on ABI-size was simplified to a direct abiSize() call.
We also enabled all the newly passing test cases and disable them for all non-passing backends.
All of those test cases were verified to see if they perhaps already pass for the c-backend.
Instead use the standarized option for communicating the
zig compiler backend at comptime, which is `zig_backend`. This was
introduced in commit 1c24ef0d0b09a12a1fe98056f2fc04de78a82df3.
Previously, this function would return an incorrect result for structs
and unions which did not have their fields resolved yet.
This required introducing more logic in Sema to resolve types before
doing certain things such as creating an anonmyous Decl and emitting
function call AIR.
As a result a couple more struct tests pass.
Oh, and I implemented the language change to make sizeOf for pointers
always return pointer size bytes even if the element type is 0 bits.

Master branch added `try` to a bunch of testing function calls, and some
lines also had changed how to refer to the native architecture and other
`@import("builtin")` stuff.
